4,4′ – DIHYDROXYDIPHENYLMETHANE: Hoʻohana nui ʻia akā he mea hopohopo nā pilikia olakino

ʻO kahi mea kemika i hoʻohana nui ʻia ma nā ʻano he nui o ka ʻoihana a me ke ola o kēlā me kēia lā e huki nei i ka manaʻo nui mai ka lehulehu a me ke kaiāulu ʻepekema.

I. 4,4′ – DIHYDROXYDIPHENYLMETHANEHe ākea nā noi. Ma ke kahua ʻoihana, ʻo 4,4′ – DIHYDROXYDIPHENYLMETHANE kahi mea maka koʻikoʻi no ka hana ʻana i nā resins epoxy hana kiʻekiʻe. Hoʻohana nui ʻia kēia ʻano resin epoxy i nā ʻoihana uila a me nā mea hana uila. No ka laʻana, i ke kaʻina hana o nā papa kaapuni paʻi (PCB), ʻo 4,4′ – DIHYDROXYDIPHENYLMETHANE – ʻano epoxy resins, me ko lākou mau waiwai uila, mechanical a me ka wela maikaʻi loa, hiki ke hōʻoia i ka hana paʻa o nā ʻāpana uila i nā wahi hana paʻakikī. I ka ʻoihana kūkulu hale, he kuleana koʻikoʻi nō hoʻi nā mea i loaʻa iā 4,4′ – DIHYDROXYDIPHENYLMETHANE. Hoʻohana ʻia lākou e hana i nā uhi hana kiʻekiʻe a me nā mea hoʻopili, hiki ke hāʻawi i ka lōʻihi a me ka hoʻopili maikaʻi, e hoʻolilo ana i ke ʻano hale i mea paʻa a me ka pale ʻana o waho o ka hale i mea lōʻihi. Eia kekahi, ke puka mai nei ʻo 4,4′ – DIHYDROXYDIPHENYLMETHANE i nā ʻoihana hana kiʻekiʻe e like me ka hana kaʻa a me ka aerospace. No ka laʻana, i ka pale ʻana i ka uhi ʻana o nā ʻāpana kaʻa a me ka hoʻopaʻa ʻana o nā lako aerospace, ua kōkua ʻo 4,4′ - DIHYDROXYDIPHENYLMETHANE i ka hoʻomaikaʻi ʻana i ka hana huahana.

II. Hoʻāla nā pilikia olakino i nā hopohopo. Eia nō naʻe, i ka hohonu ʻana o ka noiʻi, ua hoʻomaka nā pilikia olakino o 4,4′ - DIHYDROXYDIPHENYLMETHANE e hoʻāla i ka makaʻala o ka poʻe. Ua hōʻike ʻia kekahi mau haʻawina ʻepekema he nui nā waiwai endocrine - hoʻopilikia o 4,4′ - DIHYDROXYDIPHENYLMETHANE e like me 4,4′ - DIHYDROXYDIPHENYLMETHANE (BPA). Hiki i nā mea hoʻopilikia endocrine ke hoʻopilikia i ka ʻōnaehana endocrine kanaka a hoʻopilikia i ka hana huna maʻamau a me nā hana hoʻoponopono o nā hormones. Ua hōʻike kekahi mau hoʻokolohua holoholona e hiki i nā holoholona hoʻokolohua i hōʻike ʻia i ke kaiapuni 4,4′ - DIHYDROXYDIPHENYLMETHANE ke loaʻa ka ulu ʻana o ka ʻōnaehana hānau, ka hana ʻole o ka thyroid a me nā hanana ʻē aʻe. ʻOiai ʻaʻohe hōʻike pololei i kēia manawa i loko o kānaka, i ka nānā ʻana i nā hopohopo olakino i hoʻokumu mua ʻia e 4,4′ - DIHYDROXYDIPHENYLMETHANE a me ke ʻano like o nā ʻano kemika o 4,4′ - DIHYDROXYDIPHENYLMETHANE a me 4,4′ - DIHYDROXYDIPHENYLMETHANE, ʻaʻole hiki ke hoʻohaʻahaʻa ʻia kēia pilikia kūpono.

III. Ka nānā ʻana a me nā hana kūʻē. Ma muli o nā pilikia olakino hiki ke loaʻa i ka 4,4′DIHYDROXYDIPHENYLMETHANE, ua hoʻomaka kekahi mau ʻāina a me nā wahi e hoʻoponopono iā ia. Ke hoʻokumu nei nā keʻena pili i nā kūlana kaiapuni koʻikoʻi a me nā kūlana palekana huahana e kaupalena i ka hoʻohana ʻana o 4,4′ - DIHYDROXYDIPHENYLMETHANE i kekahi mau huahana e pili kokoke ana i ke kino kanaka. Ma ka ʻaoʻao ʻoihana, ke ʻimi nei kekahi mau ʻoihana kemika a me nā ʻoihana noi ma hope o ka hana i nā koho ʻē aʻe i ka 4,4′ - DIHYDROXYDIPHENYLMETHANE, ʻoi aku hoʻi ma nā kahua me nā koi palekana kiʻekiʻe loa e like me ka ʻōpala meaʻai a me nā huahana a nā keiki. Ke hoʻoikaika nei nā limahana R & D e ʻimi i nā mea hou e hiki ke hoʻokō i nā koi hana huahana me ka hōʻoia ʻana he aloha lākou i ke olakino kanaka a me ke kaiapuni. He kuleana koʻikoʻi ko 4,4′ - DIHYDROXYDIPHENYLMETHANE i ka hoʻomohala ʻoihana, akā pono e noʻonoʻo pono ʻia kona mau pilikia olakino. Me ka hoʻomau ʻana o ka noiʻi ʻepekema a me ka hoʻomaikaʻi mālie ʻana o nā hana hoʻoponopono, ua manaʻolana ʻia e hiki ke hoʻemi ʻia ka pōʻino i ke olakino kanaka a me ke kaiapuni, ʻoiai e hoʻohana ana i kona mau pono.
